The following parameters are recorded on a gas turbine test rig. Stage-1: Inlet temperature is 5000C, Inlet pressure is 650kPa. Exit gas pressure 150kPa. Determine the exit gas temperature for isentropic process. Stage-2 Gas is again heated to 4500C by constant volume process. Assume R=287 J/kg.K; Determine the heat added to the gas assuming Cp/Cv=1.4 and Cp/Cv=1.3; Draw the T-S diagram for the above process
